WATER-HEATER.

Specification of Letters Patent.

Patented Oct. 2'7, 1914.

Application filed January 16, 1914. Serial No. 812,512.

To all whom it may concern Be it known that 1, JOHN NEILAN, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in \Vater-I-Ieaters, of which the following is a specification.

This invention relates to boilers or kettles for heating water and will be particularly serviceable where small quantities of hot water are necessary from time to time, as in bath rooms, barber shops and the like.

The object of the invention is to provide improved means for heating a relatively small quantity of water to a high temperature, without bringing all the water in a reservoir to the same temperature, means being provided to draw the water from the hot water chamber as desired and to replace the same by addition of water drawn from the reservoir.

The invention is illustrated in the accompanying drawings in which Figure 1 is a vertical section of the water heater or boiler. Fig. 2 is a section on the line 22 of Fi 1.

Referring specifically to the d 'awings, A indicates a reservoir in the form of a kettle or boiler which may be made portable it desired, and which may be filled by removing the cover a at the top. Inthe bottom of this vessel is a dome-shaped partition 6 forming a chamber 13 thereunder, and the reservoir A communicates with the chamber B through openings 7 in said partition (3, said openings being located at or near the bottom of said chamber. The bottom plate 20 of the vessel is provided with a heat dome or recess 9 from whiclrheat tubes 21 extend outwardly through the chamber B and through the partition 6 and the side wall of the vessel, permitting the products of combustion to pass from the heat dome through the heating chamber B and out at the sides of the vessel.

Within the chamber B, directly above the dome 9, is a dome shaped partition 8, forming a hot water chamber C of relatively small capacity, and this communicates with the chamber B through openings 10 near the lower edge of the partition 8 and is also provided with a discharge pipe 11 leading out wardly through the side of the vessel to a faucet 12. The partition 8 has a steam vent i3 apev the top, communicating with the cham- Tn the operation of the device, the reservoir A is filled with cold water which passes through the openings 7 and 10 to the chambcrs B and C respectively. On the applica tion of heat, the water in the chamber (3, being exposed to the hottest part of the flame, and being relatively small in quantity, becomes very hot, and may be drawn 011' at the faucet 12 as fast as needed. The water in the chamber B is warmed to a considerable extent, and as fast as the hot water is drawn from the chamber C it is refilled by water entering through the openings 10 from the chamber B, which in turn is supplied from the reservoir A through the openings 7 There is no circulation between the chambers A and B, that is, hot water cannot pass from the latter to the former, and hence it is trapped in the chamber B so that the whole body of water in the vessel does not have to be heated to the temperature desired; and similarly there is only a slight circulation between the chambers B and C, and the water in the latter can be brought practically to the boiling point and so maintained while it is drawn oil, the relatively warm water in the chamber B flowing in as fast as the hottest water is drawn oli.

The device will be found very serviceable for giving a quick and practically continuous supply of hot water from a portable vessel or reservoir, and without the cost for fuel required to heat all the water in the reservoir.

That I claim as my invention is:

1. A water heater comprising a vessel having an upper cold water reservoir, a lower warm water chamber and a passage connecting the reservoir and the bottom of the chamher, and a hot water chamber located adjacent to the warm water chamber and having a passage communicating with the latter, and means to draw water from the hot water chamber.

2. A water heater comprising a vessel having an upper chamber A for cold water, and a lower warm water chamber B, a partition between said chambers, having an opening therethrough near the bottom of said lower chamber, a heat dome in the bottom plate of the vessel, a partition above said dome over the hot water chamber C, said partition having an opening 10 near the bottom of said chamber C, and means to draw water from said chamber G.

3. A water heater comprising a. vessel having an upper reservoir A for cold water, a lower chamber for warm water, and a paspartition therein over a lower warm water sage connecting the reservoir and the lower chamber 13, with an opening in said partipart of the said chamber, a heat dome in the 15 tion near the bottom of said chamber, a heat bottom of said vessel, and tubes extending 5 dome in the bottom plate of the vessel a parfrom said dome through said chamber to the tition above said dome over the hot water sides of the vessel. chamber C, said partition having an opening In testimony whereof, I do afix my signa- 10 near the bottom of said chamber 0, and a ture in presence of two witnesses.

vent 13 at the top of said chamber C, and JOHN NEILAN. 10 means to draw water from said chamber C. Vitnesses:
